I am experiencing a bit of a learning curve using an electric drill to roll crimp some 3" .410 Turns out I used a little too much force and fattened the outside diameter of the finished hull so they were sticky chambering. Got looking at rifle case measurements and not owning a .444 Marlin die utilized plan "B". I took the de-priming stem out of a 30-06 FL RCBS sizing die and used a # 4 RCBS shellholder . Using LEE lube lightly finger applied to the first 1" of the hull. Sliding it into the die about 2/3 of the way and presto drops right into the .410 chamber. Relieved after fixing about 250rds.....better than having to take them apart.Never too old to learn.
